FORT COLLINS — This third annual USA Pro Challenge is turning into a Slovakian folk dance. Peter Sagan won his third stage in six days Saturday on a week-long course so mountainous it scared away every top sprinter in the world. Every one but the Slovakian, Peter Sagan.

He easily won a bunch sprint after 115.2 miles from Loveland to Fort Collins.

“I came here to prepare for Quebec (Grand Prix) and I’ve won three stages,” Sagan said. “I’m very happy and a little surprised.”

He shouldn’t be. Not one of the 129 other riders in this field had ever beaten him in a sprint finish. Then again, this isn’t cherry picking. He has won 17 times this year.

They did try, however. Rory Sutherland, the Australian for Team Saxo-Tinkoff, took the lead with 500 yards to go but Sagan easily caught and passed him to the line.
